For packing and selling grapefruit in 1-3/5 bushel wirebound boxes, houses in the smallest volume group had total costs of only 29 cents above the average cost, while those in the largest volume group had costs about 6 cents less than the average. The range in total costs this season was extreme on the high side, but with little change from the preceding season in the lowest costs. Materials cost did not seem to vary with size, and total labor costs were not closely related to volume by groups. The other direct operating costs and the indirect or fixed costs did, in general, de- crease by size groups. There were packinghouses that had high as well as low .:e>s in each volume group. This variation within groups is shown in Tables 10 and 11 for 1-3/5 bushel wirebound boxes and indicates that the larger volume groups contained more houses with low cents than the smaller seasonal volume groups.
